I'm having an issue in synchronising my Blackberry Classic with Outlook.

All my diary entries on my Blackberry have been removed, both future and past, but they are still on Outlook. I have not seen this problem before this morning when I tried to synch for the week ahead. I have re-checked and downloaded Blackberry link and verified that I have connections from PC to device through cable and Bluetooth.

BlackBerry Link is now out of date and no longer works for many people with updated versions of Windows 7, Windows 10, and Mac OS.

Your best solution at this point is to sync both Office Outlook on your PC and your Classic's Contacts and Calendar through Outlook.com. It works very well once you get it setup, automatically updates, usually within seconds, and you always have a cloud backup of your contacts and calendar events.
